TECHNICAL FIELD

The disclosure relates to the technical field of photovoltaic power generation, in particular to a photovoltaic assembly convenient for angle adjustment.

BACKGROUND

Solar cell assembly (also called solar cell panel) is the core and the most important part of solar power generation system. Its function is to convert solar energy into electric energy, or send it to a storage battery for storage, or push the load to work. For photovoltaic power plants, the amount of solar radiation is very important, which determines the power generation of the power plant, and the amount of solar radiation is directly related to the installation direction and angle of solar panels. Therefore, when installing solar panels, we need to pay attention to the selection of the best orientation and the best inclination angle. However, the traditional mounting frame of photovoltaic panels is generally fixed in angle, so it is impossible to adjust the angle to achieve the best inclination angle, which will affect the total power generation.

Obviously, the described embodiments are a part of embodiments of the disclosure, but not all of embodiments. Based on the embodiments in the disclosure, all other embodiments obtained by ordinary skilled in the field without creative efforts belong to the scope of protection of the disclosure. Referring to FIGS. 1 - 10 , in order to improve the above problems, the disclosure provides a photovoltaic assembly convenient for angle adjustment, which includes a photovoltaic mounting base and a photovoltaic mounting frame; where, the photovoltaic mounting base is fixed on a fixture and is used for providing an installation station; the photovoltaic mounting frame is detachably mounted on the photovoltaic mounting base and is capable of adjusting angle, and a mounting end of the photovoltaic mounting frame is capable of adjusting mounting size and is used for mounting photovoltaic panels. Specifically, the photovoltaic mounting base includes first slideway parts 1 , first connecting mechanisms 2 and a connecting beam 3 ; where, two first slideway parts 1 are arranged in parallel; each of the first slideway parts 1 has a U-shaped structure, a top of each of the first slideway parts is open, and inner walls of opposite side walls of each of the first slideway parts are provided with a plurality of limiting grooves arranged in parallel, and the limiting grooves are matched with detachable first limiting parts 10 ; a plurality of limiting areas are formed by the first limiting parts 10 ; at least two first connecting mechanisms 2 , where the first connecting mechanisms are arranged in corresponding limiting areas of the two first slideway parts 1 ; side walls of the first connecting mechanisms 2 are detachably connected with each of the first slideway parts 1 through second connecting mechanisms 4 ; a connecting beam 3 , where two ends of the connecting beam 3 are respectively connected to a top of corresponding one of the first connecting mechanisms 2 , the connecting beam is perpendicular to the first slideway parts 1 ; a photovoltaic mounting frame is installed on the connecting beam 3 . Specifically, the limiting groove is a groove structure with a T-shaped cross section, the first limiting part 10 is a plate structure, and both ends of the first limiting part 10 are T-shaped structures adapted to the limiting groove, which can penetrate along the top of the limiting groove. Every two first limiting parts 10 will separate a limiting area with the same size as the first connecting mechanism 2 , and the first connecting mechanism 2 is embedded in the limiting area. Through this scheme, the installation position of the first connecting mechanism 2 on the first slideway part 1 can be changed, so as to be suitable for the situation that the position of the photovoltaic panel needs to be fine-tuned in the installation process, providing more position selectivity and stronger adaptability. Specifically, the first connecting mechanism 2 includes a connecting base 20 , a sliding frame 21 , an accommodating chamber 22 , a rack part 23 , a connecting rotating shaft, a gear part 24 and spring coiling mechanisms 25 ; where, a top of the connecting base 20 is provided with a first sliding groove, an annular second sliding groove 200 is arranged outside the first sliding groove, and an inner wall of the second sliding groove 200 is provided with a limiting protrusion; the sliding frame 21 has a cylindrical structure and a middle of the sliding frame is provided with an extension rod 210 ; the extension rod 210 extends along the first sliding groove, a middle of an out wall of the extension rod 210 is connected with an extrusion plate 211 , and the extrusion plate 211 is provided with a through hole; a top of the sliding frame 21 is detachably connected with the connecting beam 3 , the outer wall of the sliding frame is slidably connected with the limiting protrusion, and a bottom of the outer wall of the sliding frame is provided with a limiting baffle, the limiting baffle is connected with a bottom of the second sliding groove 200 through a spring part; flexible buffer pads 212 are arranged between an inner wall of the sliding frame 21 and the extension rod 210 ; the buffer pads 212 may preferably be rubber pads; a top of the first sliding groove is provided with an expansion area, where an accommodating chamber 22 is embedded in the expansion area and sleeved outside the extension rod 210 to form a sliding sealing structure with the outer wall of the extension rod 210 ; the accommodating chamber 22 is filled with a buffer medium, and the extrusion plate 211 is located in the accommodating chamber 22 , and the extrusion plate 211 is capable of reciprocating in the buffer medium; a rack part 23 vertically connected to a bottom of the extension rod 210 ; the connecting rotating shaft is rotatably connected to opposite side walls of the first sliding groove and is opposite to the rack part 23 ; the gear part 24 is fixed at a middle of the connecting rotating shaft and is is meshed with the rack part 23 ; the spring coiling mechanisms 25 are arranged two and are respectively sleeved at positions close to two ends of the connecting rotating shaft, and outer walls of the spring coiling mechanisms are fixed with an inner wall of the first sliding groove; when the gear part 24 and the rack part 23 are displaced relative to each other, the spring coiling mechanisms 25 are stressed and provide a reset reaction force. Specifically, the buffer medium can preferably be a flexible mastic material, which can buffer through the through hole of the extrusion plate 211 . It should be understood that in the above scheme, when the photovoltaic mounting frame is subjected to external force, it will drive the connecting beam 3 to shake and press the sliding frame 21 to reciprocate. In the process of action, the downward movement of the sliding frame 21 can drive the rack part 23 to move downward, and then drive the gear part 24 to rotate, and finally the spring coiling part 252 in the spring coiling mechanism 25 will twist under the external force. The reaction force of the spring coiling part 252 can offset the external force and reduce the impact on the sliding frame 21 . Moreover, during the downward movement, the extrusion plate 211 outside the extension rod 210 will press the buffer medium in the accommodating chamber 22 , which also plays a role in buffering the impact force, improving the bearing strength against external force and ensuring the service life. When the external force disappears, the above parts are reversely reset under the reaction force of the spring coiling part 252 until they are restored to the original state. The outer wall of the sliding frame 21 and the second sliding groove 200 are in a sealed state, which can prevent impurities such as dust from entering the interior and polluting the outer wall of the extension rod 210 , thus blocking the sliding, the use effect is improved and the maintenance frequency is reduced. In the preferred embodiment of the photovoltaic assembly convenient for angle adjustment, the number of the second connecting mechanisms 4 is two, the second connecting mechanisms are respectively arranged on both sides of the first connecting mechanism 2 . The second connecting mechanism 4 includes a fixed shaft and rotating plates 40 . The fixed shaft is vertically fixed on a side wall of the connecting base 20 of each of the first connecting mechanisms 2 ; the number of the rotating plates 40 is two, where and ends of the two rotating plates 40 are rotatably connected with the fixed shaft respectively; other ends of the two rotating plates 40 are hinged with a first U-shaped frame 41 ; the side walls of the first U-shaped frame 41 and the first slideway part 1 are both provided with suitable connecting holes; an open end of the first U-shaped frame 41 extends along the side wall of the first slideway part 1 , and the first U-shaped frame 41 and the first slideway part 1 are detachably connected through bolts and the connecting holes. In the above scheme, the freedom degree of the first connecting mechanism 2 in the vertical direction can be limited, and the first connecting mechanism 2 can be prevented from being separated from the first slideway part 1 . When disassembly is required, only the bolts on the first U-shaped frame 41 need to be removed, so that the rotating plate 40 can be rotated, and the first U-shaped frame 41 can be separated from the first slideway part 1 . At this time, it can be taken out only by pulling up the first connecting mechanism 2 , which is very convenient and has low realization difficulty. Specifically, the spring coiling mechanism 25 includes a fixed inner cylinder 250 , a fixed outer cylinder 251 , a spring coiling part 252 , elastic pulling plates 253 and an elastic filler; where, the fixed inner cylinder 250 is sleeved and fixed on an outer wall of the connecting rotating shaft, the fixed outer cylinder 251 is sleeved outside the fixed inner cylinder 250 to form an inner cavity inside, and an outer wall of the fixed outer cylinder 251 is fixed with the inner wall of the first sliding groove, the fixed inner cylinder 250 is capable of rotating relatively with the fixed outer cylinder 251 , an inner end of the spring coiling part 252 is connected with the fixed outer cylinder 250 , and an outer end is connected with the fixed outer cylinder 251 , and a plurality of the elastic pulling plates 253 are arranged inside the spring coiling part 252 and are connected with a corresponding inner wall of the spring coiling part 252 ; the elastic filler is filled in the inner cavity. Specifically, the elastic pulling plate 253 may be an elastic rubber plate, and the elastic filler may be a round ball made of rubber material. It should be noted that when the gear part 24 rotates, it can drive the connecting rotating shaft and the fixed inner cylinder 250 to rotate synchronously, so that the spring coiling part 252 is curled and deformed, and the curled and deformed spring coiling part 252 will squeeze the elastic filler. The elastic filler is deformed by external force, and the deformation of the spring coiling part 252 will pull the elastic pulling plate 253 to deform. The forces generated by the deformation of the elastic pulling plate 253 , the elastic filler and the spring coiling part 252 will force the spring coiling part 252 to return to its original state, so that the rotating force in the opposite direction is applied to the connecting rotating shaft and the fixed inner cylinder 250 to counteract the external force and offset the external force, thereby realizing the buffering of the impact force and being beneficial to the long-term use of the whole device.
